The piston is out its the loose keyway that fits into the piston that is stuck to the bottom of the chamber. I have poured some WD40 in to see if that gets through.
I have seen all the spares are on Knibbs I was just wondering if I could make some, I can see me eventually getting some or selling the gun as spares or repair with a note explaining the problems.
Thanks for the input though it's appreciated.
Cheers
